Space Shuttle and 747 Mating: In Depth Look

The orbiter and its flying taxi, a retrofitted jumbo 747, have shared many a flight. Take a look at the history and development of the Mate-Demate Device (MDD) and catch a time-lapse of the joining of these two massive aerial machines.

Gigantic Moon or Dwarf Planet?

The second largest moon in our Solar System has one of the supposed primary requirements for life: an active liquid cycle. But Titan’s liquid isn’t water.

Under the Namibian Sky

The night sky of Namibia is one of the best in the world, about the same quality of the deserts of Chile and Australia. This 13 min video contains about 250 hours of actual exposures, gathered at Tivoli Farm, Namibia, during 10 perfectly cloudless nights.

Geostationary Satellites Beyond the Alps

Why don’t those stars move? Stars in the sky will typically appear to rise and set as the Earth turns. Those far to the north or south will appear to circle the pole. If you look closely at the above time-lapse movie, however, there are points of light that appear stationary. These objects are not stars but human-launched robotic spacecraft that remain fixed high above the Earth’s equator.

Called geostationary satellites, they don’t fall down because they do orbit the Earth — they just orbit at exactly the same speed that the Earth rotates. The orbital distance where this is possible is much farther than the International Space Station but much closer than the Moon.

The video was taken from one of the highest revolving restaurants in the world located on the Mittelallalin in the Swiss Alps. In the foreground is a mountain known as the Allalinhorn. An even closer inspection will show that the geostationary satellites flash with glints of reflected sunlight. The satellites also all appear on a single line — actually the projection of the Earth’s equator onto the sky.

SDO and STEREO Spot Something New On the Sun

The changes of a coronal cell region as solar rotation carries it across the solar disk as seen with NASA’s STEREO-B spacecraft. The camera is fixed on the region (panning with it) and shows the plumes changing to cells and back to plumes again — based on the observatory’s perspective — during the interval June 7-14, 2011.

The pattern of cells with bright centers and dark boundaries occurrs in the sun’s atmosphere, the corona. These cells looked somewhat like a cell pattern that occurs on the sun’s surface — similar to the bubbles that rise to the top of boiling water — but it was a surprise to find this pattern higher up in the corona, which is normally dominated by bright loops and dark coronal holes.

End of the Space Shuttle Ferry Era - Final Flights

A pair of retrofitted jumbo 747’s carried the orbiters cross country on many occasions. With the retirement of the Space Shuttle program, they’ll make their final deliveries of Discovery, Endeavour and Enterprise to their new museum homes.

ISS from Atlantic Ocean to Ukraine

This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken March 10, 2012 from 07:42:00 to 07:59:44 GMT, on a pass from the North Atlantic Ocean, west of Liberia, to central Ukraine, north of the Black Sea.

This video begins as the ISS heads over the terminator line, separating night and day on the Earth. As the pass continues over land, there is quite a bit of haze blocking the view of land, until the ISS continues over the clay-colored sands of northern Africa. The pass ends as the ISS is looking back at the Balkan Peninsula under heavy cloud.

Heading Towards Aurora Australis

This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken March 10, 2012 from 14:49:58 to 15:06:09 GMT, on a pass from the Indian Ocean, southwest of Australia, to southern New Zealand.

This video mainly focuses on the dynamic motion of the Aurora Australis over the Indian Ocean. The video begins far enough away from the aurora so it is easy to see the underside, and as the ISS flies over, the camera captures the motion of the aurora from the top.

Waves by Daniel Palacios

'Waves' utilizes a basic construction of a long piece of elastic string and two motors to visualize the presence of people close to the installation. The string between the two motorized chambers reacts to the people presence and movements, it twirls to produce a sine-wave simulation that eloquently resembles both the digitization of real-time sound waves and patterns of flow and connectivity found in natural systems.

Blowing Through Space

A week of images from one of two STEREO Heliospheric Imagers on its ‘Behind’ spacecraft reveals at least half a dozen coronal mass ejections (CME’s) blowing out from the Sun and heading into space (Mar. 25 - April 2, 2012).

This imager is a wide-angle visible-light imaging system for the detection of CME events in interplanetary space and, in particular, of events directed towards the Earth. In this movie the Sun is just to the left of the field of view and the Earth would be millions of miles to the right.

Mercury is the bright object moving from right to left against the background of stars near the center of the images. The Sun has been busy popping off solar storms like these as it approaches the maximum of its 11 year activity cycle. The period of peak activity is predicted to occur in about a year.

Up the East Coast of North America

This video was taken by the crew of Expedition 30 on board the International Space Station on January 29, 2012 from 05:33:11 to 05:48:10 GMT, on a pass from just southwest of Mexico to the North Atlantic Ocean, northeast of Newfoundland.

This pass begins looking over Central America towards the Gulf of Mexico and the southeastern United States. As the ISS travels northeast over the gulf, some southeastern United States cities can be distinguished, like New Orleans, Mobile, Jacksonville, and Atlanta.

Continuing up the east coast, some northeastern states, like Washington, D.C., Baltimore, Philadelphia, and New York City stand out brightly along the coastline. The Aurora Borealis shines in the background as the pass finishes near Newfoundland.

Physicists Bring Origins of Universe to Big Screen

Dramatic 3-D videos, created from actual data by Stanford physicists at SLAC’s Kavli Institute for Particle Astrophysics and Cosmology, show the origins of the universe. Now playing to the general public on screens at the SLAC National Accelerator Laboratory campus, as well as museums in San Francisco and New York.
